The treaty that marked the end of Cold War tensions between East and West is the Intermediate-Range Nuclear Forces Treaty (INF Treaty), signed in 1987 between the United States and the Soviet Union. This agreement aimed to eliminate intermediate-range and shorter-range missiles and is significant as a step towards reducing the nuclear arms race. It represented a thawing of relations during a period marked by mutual suspicion and competition. The treaty led to the destruction of thousands of missiles and was a key factor in easing tensions, contributing to the eventual dissolution of the Soviet Union.
